A straightforward synthesis of new thiol derivatives incorporating the tetrathiafulvalene (TTF) moiety is presented. These electroactive systems form highly stable self-assembled monolayers (SAMs) on gold electrodes. The electrode obtained by SAM formation from a thiol derivative whose structure associates the redox-active TTF unit and a crown-ether ligating part, allows the voltammetric recognition of barium.

Synthesis of thiol-containing amino acids through alkylation of glycinate ketimine
Zhi, Jian,Xiao, Yuli,Hu, Aiguo
experimental part, p. 914 - 920 (2012/01/15)
A general synthetic route for the synthesis of thiol-containing amino acids through alkylation of glycinate ketimine followed by hydrolysis was developed in this work. The common problems associated with the instability of ketimines and thioesters were so
Electrochemical cleavage of azo linkage for site-selective immobilization and cell patterning
Jung, Hyun Joo,Min, Hyegeun,Yu, Hyunung,Lee, Tae Geol,Chung, Taek Dong
supporting information; experimental part, p. 3863 - 3865 (2010/07/13)
A new molecular structure of azobenzene, which can be reduced to the corresponding anilines at a low reduction potential for the site-selective immobilization of biomolecules, is proposed. Redox-active species, enzymes, peptides, and cultured hippocampal neurons can be effectively immobilized on the electrochemically activated surface.
Synthesis, structure, and chemistry of new, mixed group 14 and 16 heterocycles: Nucleophile-induced ring contraction of mesocyclic dications
Block, Eric,Dikarev, Evgeny V.,Glass, Richard S.,Jin, Jin,Li, Bo,Li, Xiaojie,Zhang, Shao-Zhong
, p. 14949 - 14961 (2008/02/04)
More than 40 new 4- to 12-membered ring heterocycles containing various combinations of Group 14 and 16 elements Si, Sn, S, Se, and Te have been synthesized and fully characterized. Synthesis of these small-ring as well as medium-ring (mesocyclic) heterocycles from α,ω-dihalides is facilitated by the presence of gem-dialkylsilyl and gem-dialkylstannyl groups in the precursors. Conformations of several of the new ring systems in the solid state have been determined by X-ray crystal structure analysis. Oxidation of mixed S(Se, Te)/Si eight-membered ring mesocycles with NOPF6 or Br2 gives dications or a bicyclic dibromide, respectively, which can be characterized by NMR methods. On treatment with nucleophiles, mesocyclic dications, or the corresponding radical cations undergo ring contraction, giving five- or six-membered ring heterocycles. Photolysis of a S/Se four-membered ring heterocycle gives selenoformaldehyde, trapped in 80% yield with 2,3-dimethyl-1,3-butadiene.
Preparation of ω-tetrahydropyran-2-ylsulfanylalkylmagnesium chlorides: Useful reagents for the synthesis of 1-(ω-mercaptoalkyl)-1,2- dihydrobuckminsterfullerenes (C60)
Kim, Sung Hoon,Lee, Sung Han,Kang, Seung Hoon
, p. 9693 - 9696 (2007/10/03)
ω-Tetrahydropyran-2-ylsulfanylalkylmagnesium chlorides are prepared as Grignard reagents containing protected mercaptoalkyl chains, which are useful for the direct introduction of ω-mercaptoalkyl chains to electrophiles. In order to prove the usefulness of these reagents, they were reacted with buckminsterfullerene (C60) to give 1-(ω-mercaptoalkyl)-1,2- dihydrobuckminsterfullerenes after the deprotection of THP group with TFA.
